trapecia [35]
In this problem it states that one tenth or only 10% is Canada’s population to the United States. Hence with the steps we can identify the population of the United States.
<span><span>1.       </span>10 % = 32 million or 0.1 = 32 million</span>
<span><span>2.       </span>Then 32 million / 0.1 = 320, 000, 000 million</span>

Therefore there are 320, 000, 000 million living in the United States
Adding one zero. Why the zeroes? It is the result because of the power of 10 in a hundred percent population coming from the Canada’s population. Take note that 100% = 320, 000, 000 million of the USA while 10% of it is Canada so we divide it by 0.1 which is 32, 000, 000 (the power of ten)

Find the average of the following salaries:<br> $38,750.00, $42,500.00, $44,500.00
sertanlavr [38]
To find the average you add all three numbers together and then divide by three since you added three.
$38,750.00 + $42,500.00 + $42,500.00 = $123,750.00
$123,750.00 ÷ 3 = $41,250
So your answer is $41,250
